Kingston 2 gb ram 800 mhz on d946gzis intel org. board.

pls explain this some one..

well can this work any how .....like 1 channel or half of it.

The first screenshot shows that your RAM stick is working alone in single-channel mode. This has nothing to do with the RAM being DDR or DDR2. Double Data Rate (DDR) and dual-channel mean different things. If you put in another stick of the same type, then they can work together as a pair in dual-channel mode (if your motherboard supports dual-channel operation). This will give a slight boost in speed.

All DDR (1,2 & 3) RAMs process data at twice the clock frequency. DDR2/800 operates at an actual clock frequency of 400 MHz. So the info on the second screenshot is also correct. But since your motherboard provides only up to 333 MHz, your memory is working at DDR2/667 speed. IOW, the RAM is being underclocked. No harm in that. The difference is that it is not working at its full potential.

The first screenshot shows the actual operating frequency and timings of the RAM while it is being used in your computer. The second screenshot shows the specifications of your RAM.

PC2-6400 is another name for DDR2/800. In the same way, PC3200 is another name for DDR400 (the older DDR1). The basic clock for DDR400 is 200 MHz, but since it is a Double-Data Rate memory, it processes data twice in one clock cycle, so it is effectively operating at 400 MHz.

so in short I don't have to worry about this

ram is atleast working on 667 MHZ .. My M.B maximum support

So no problem for me now or in future.
